    I have a LED 80 watt yard light with a sold state circuit board bad capacitors

    This light got to where it would turn on when it felt like it ( photo cell controller board issue )

    It has one 47uf@50 volts and one 10uf@50 volts double rating on the ESR reading ( non brand name capacitors )

    Now every time I cover the photo cell and remove cover it turns on and turns off like it should

    I will try to take a picture of the little board before I put it back together

      I used to run through bags of these photo cells. These days I am way too busy to bother with them.

          At first I thought it might have been the photo cell but when I saw this circuit and how it was setup I just replaced the capacitors first and see what happened next when it now respond to light and darkness I knew that what the problem was

                  I have torcher tested yard light for a week now and it has been running flawlessly so this has been a successful repair

                  I been using it with the photo in the dark then every once in awhile I shine a light on the photocell and shuts right off then remove the light from the photocell and turn right back on

                      by m1ch43lzm
                      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                      Problem

                      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                      by howardc64
                      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                      Engineering help - how does the charging circuit on this board work?
                      by repair-it
                      This board attaches to 2 12v batteries in tandum (Black/Red squares). There is a 24v power supply that attaches at the 2 pin molex connector (circled in red). I need help to determine which components run the charging circuit in an effort to determine a point of failure. There are multiple via's, making it difficult to trace the circuit. Nothing appears to be shorted but I wasn't able to fully test as I do not have 2 12v batteries available. My assumption is that the micro controller (red question mark) determines when to turn the charging circuit on & off. I'm pretty sure a regulator and...

                      How to test circuit board battery connection.RS-4i sequential stimulator
                      by Crrose
                      Not sure where to post this but I have an RS-4i sequential stimulator that runs off rechargeable batteries and also has a VL2330 coin cell battery that retains the memory. If that battery doesn't hold charge or connection is bad then the unit will power on and say to recharge. Once it is charged it indicates it is charged but when you turn unit on it powers off saying to charge batteries. I replaced that coin cell battery and now it won't even indicate batteries need to be charged. I have tested the battery pack and it is fully charged at 6V but the coin cell only shows 2.97V which is a brand...
